4–20 mA, RTD, PLC & Encoder Calculators for Instrument Technicians
Twenty-two free calculators across signal scaling, loop power, RTD temperature, encoders, calibration, and sensor mapping. Type the nameplate numbers, read the engineering value, verify against the manual — every output labeled, every formula visible.
Method
Inputs in. Math shown.
02 · Math
Every output labeled.
mA, ohms, counts, percent FS. Each with its formula.
03 · Verify
Field-check before relying.
Manuals, calibrator data, nameplates. Verify before relying.
